Chaleur meurtriere

It is a very hot summer in the city as the well known detectives of the 87th Precinct investigate serial rapes and a mysterious homicide (which do not appear to be connected). The victims appear to have been raped by someone who attacked them earlier and wasn't caught. Detective Eileen Burke, who is working together with detectives Carella, Meyer and Brown, goes undercover and pretends to be one of the women who was raped earlier in order to lure out the rapist. Her boyfriend, Det. Kling, is not happy with her assignment.
